Mid-Level Backend Developer Role

Role Overview

A Mid-Level Backend Developer at Cosmoquick is responsible for building and maintaining the server-side logic that powers the AI hiring platform. Day-to-day, the employee designs APIs, optimizes database queries, and ensures the system can handle high volumes of candidate data without latency. This role has a direct impact on the product's reliability and the business's ability to deliver candidate matches in under 60 minutes. The developer acts as a critical bridge between data infrastructure and user-facing features.

Detailed Responsibilities

• Design and implement RESTful APIs for candidate data ingestion and retrieval
• Optimize SQL and NoSQL database queries to reduce latency in the talent graph
• Develop microservices for the AI-powered pre-vetting engine
• Collaborate with frontend teams to ensure seamless data integration
• Monitor system performance and troubleshoot backend issues in real-time
• Write clean, testable code with comprehensive unit and integration tests
• Participate in code reviews to maintain high standards of technical quality

Day-to-Day Workflow

The typical day starts with a team stand-up to discuss progress on the AI matching engine and any critical backend issues. Developers then spend the morning coding new microservices or refining database schemas for the talent graph. After a lunch break, the afternoon often involves debugging complex latency issues or integrating new data sources from partner job boards. The day concludes with a code review session and updating documentation for the API endpoints. This workflow ensures continuous delivery of features while maintaining system stability.

Tools and Technologies

Cosmoquick utilizes a modern tech stack tailored for high-performance data processing. The primary backend language is Python, often used with frameworks like Django or FastAPI for API development. The database layer relies heavily on PostgreSQL for structured data and MongoDB for unstructured candidate profiles. Developers also use Redis for caching to ensure the 60-minute connection speed. The platform is hosted on cloud infrastructure, likely AWS or similar, with containerization managed via Docker and Kubernetes. CI/CD pipelines are automated using Jenkins or GitLab CI.

Skills and Requirements

Technical Skills

Candidates must possess deep expertise in backend development, specifically in Python and API design. Proficiency in SQL and NoSQL databases is essential, along with the ability to optimize queries for large datasets. Knowledge of microservices architecture, caching strategies with Redis, and cloud deployment is required. Familiarity with AI/ML integration patterns is a strong plus, as the role supports the pre-vetting engine. Experience with containerization tools like Docker and orchestration with Kubernetes is also critical for this position.

Soft Skills

Effective communication is vital for collaborating with frontend teams and explaining complex technical issues to non-technical stakeholders. Strong problem-solving skills are needed to troubleshoot latency issues and design efficient data solutions. Teamwork is essential in a fast-paced environment where developers must align on shared goals for the talent graph. Adaptability is key, as the tech landscape and hiring demands change rapidly. A proactive mindset helps in identifying potential system bottlenecks before they impact the business.

Experience Expectations

Cosmoquick expects candidates to have 2–4 years of professional backend development experience. A strong portfolio showcasing real-world projects, such as API development or database optimization, is highly valued. While a specific GPA is not the primary focus, a solid academic record in computer science or a related field is beneficial. Candidates should demonstrate a history of working on scalable systems and have experience with cloud infrastructure. Internships or previous roles in high-growth tech companies are preferred.
